This invention relates to a belt buckle for use in connection with anybelt or band to which it may be found applicable by those skilled in theart.

Briefiy stated, the improved buckle comprises a backing plate withslotted ends and a maintenance or retention boss, together with acompanion clamping plate or slide having means for cam co-aotion withthe slots and a hook to accommodate an eyelet fastener, and an elongatedbelt retaining opening for cooperation with the aforesaid boss.

In carrying the principles of the invention conception into actualpractice through the instrumentality of the aforesaid structure, I haveevolved and produced a simple and economical accessory which is notpermanently connected to the end of the band but rather has adjustableconnection therewith to permit the buckle to be quickly adjusted andmaintained in the desired adjusted position.

I am aware of the fact that many types of buckles involving the campressure and clamping principle are in vogue and are found in similarWith a general knowledge of this, I have perfected a specific buckleconstituting what I believe tol be a unique contribution to the tradeand the art in that it is structurally distinguishable, positive anddependable in action, and otherwise well designed and balanced toaccomplish the desired result in a highly satisfactory manner.

In the drawings:

Figure 1 is a view showing one band-end in full lines and the companionband or strap end in dotted lines, together with the improved buckleassociated therewith.

Figure 2 is a longitudinal sectional view of the structural assemblyshown in Figure 1.

Figure 3 is a plan View of the sheet metal blank from which the backingplate is constructed.

Figure 4 is a section taken on the plane of the line 4 4 of Figure 1.

Figure 5 is an outside elevational View of the arrangement illustratedin Figure 1 showing the relationship of parts more plainly.

igure 6 is a section taken approximately on the plane of the line 6 6 ofFigure 5.

Figure 7 is a perspective view of the slidable clamping plate.

Figure 8 is an end View of the slotted flange-end of the backing plate.

In the drawings, in Figures 1, 2 and 5, a band is designated by thenumeral 9. One end portion of a complemental band or the like is shownin the drawings andis. designated by the reference numeral 1,1.. Thisband or strap end 11 is prolvided with an eyelet designated by thereference numeral 12 and also shown in dotted lines.

The improved buckle comprises two primary parts; namely the relativelystationary section 13 and the relatively movable or adjustable section14. The first-named section 13 comprises a rectangular backing plate 15constituting a part of the blank shown in Figure 3. As seen in thelast-named figure this backing plate is provided with a longitudinallyelongated outwardly pressed portion which defines a maintenance hump orboss 16.

The end portions of the plate are bent up at right angles on the scoreor fold lines 17 to form a pair of duplicate end flanges 18 havinginclined cam or binding slots 19. The complemental or companion section14 is shown in Figure '7 and comprises a suitably proportioned andShaped slide plate 20. This has a triangular end portion whose apex partis formed with an inturned keeperl hook 21 andI an associated aperture22, the hook being fashioned to permit quick releasable connection ofthe eyelet fastener 12 thereto as shown in Figures 2 and 5. The aperture22 is obviously nothing more than a clearance hole to facilitateconnection and disconnection of the features 12 and 21.

The plate is provided with integral outstanding cam lugs 23 fittedslidably in the cam slots 19 and the plate is further formed with anelongated rectangular adapter hole or opening 24 which is shaped tocorrespond with the aforementioned maintenance boss 16. The opening 24is slightly larger than the boss as is evident to permit the material ofthe band or belt to be crimped over the boss as indicated at 25 inFigure 2 whereby to force the material into the hole 24 so that it issecurely held between the two plates 15 and 20 when they are boundfirmly together by the customary cam clamping action.

It is obvious of course, that the plate 20 is In the present bucklearrangement the clamping u action is uniform, positive and dependable,such as to firmly hold the belt vend l0 in place in the mannerdescribed. Likewise, the binding or clamping action is such as to'minimize damage to the belt, strap, or band, as thecase may be.

From the foregoing description it will be observed that the principalvnovelty is predicated upon the particular construction and arrangementof the buckle irrespective of the structure with which it is used. Sucha buckle is applicable to belts, body encircling bands, straps, andsimilar accessories. In particular, a buckle of this type may well beused as a back-band buckle in conjunction with plow gear and wagonharness by merely changing the position ofv the buckle in the drawingfrom a horizontal to a Vertical position to accommodate a trace or thelike (not shown). Needless to say, however, the buckle may be used forany purpose for which it is found satisfactorily applicable.

These and rother structural, commercial and economical features havevdoubtlessr been madey apparent from the explanatory description'fwhenread in conjunction with the illustrative drawings.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

'.tWeen said flanges, said clamping plate being provided with opposedlugs having slidable cam co-action with said slots, said clamping platebeing formed with a retaining hook, and an elongated adaptation hole forco-operaton with said boss to permit a band end to be firmly clampedbetween the plates and forced by the boss into said adaptation hole.
